- Add constant `*version*' which contains the version number of the
project.
- Change `db-connect' to `check-db'. Update to using sqlite functions
instead of cl-sql ones.
- Move the bookmark collection loop to `get-bookmarks'.
- When starting up, if the length of args is greater than 1 check if
the given option is a known "command" and if so, call it with the
command line arguments (minus the first). Otherwise show all the
bookmarks.
